Danish Micro Engineering A/S

About Company

DME - Danish Micro Engineering A/S is one of the oldest manufacturers of Scanning
Probe Microscopes (see History of DME) and since 1989 active in nanotechnology.

Our instruments are characterized by the simplest possible operation combined
with the capability for a high throughput. When it comes to new developments,
we take great care to secure that the instruments will not "feel"
like a prototype afterwards. Naturally, also new developments are supported
by a corresponding software. Take cantilever change as an example: For our DS
95-AFM exchanging the cantilever takes only some seconds. Adjustment and approach
are fully automatic and optionally we also offer a full automatic cantilever
changer. Furthermore, all our AFM scanners has a built-in optics which facilitates
the location of a specific place on the sample surface. Both guarantee effcient
work and a high throughput.

Our instruments are characterized by an optimal combination of mechanics, electronics
and software. Only by in-depth harmonization of all three components a good
scanning probe microscope can be obtained. Our developers work interdisciplinary:
To make a good control software the developer must for example have also a deep
understanding of mechanics and electronics. In the same manner the mechanical
development process must consider how the electronics and software will later
control the system. Actually, the real power of our team of developers lies
in the interdiciplinary work and the permanent overview of the whole concept.

All main parts of our Scanning Probe Microscopes are of our own manufacture;
this includes the piezo motors for approach, the electronics, our software,
and naturally our mechanical design. This has the advantage that we are able
to quickly make modifcations in all parts of the instruments, should a certain
application require such.

All of our products are individually configured to meet the customer requirements.
The application is always in the foreground, not the instrument. We have a series
of Standard products that can be seen as a kind of starting point. If our product
palette does not to 100 per cent cover the application, we will modify the instrument,
and not the application. In a complex area like nanotechnology this is quite
often needed, otherwise the performance will much lower than possible. Our experienced
team can handle even the development of a fully new construction in accordance
with the customers specifications. For special applications we are in close
dialog with our customers to find out the best solution and also how to realize
it in the shortest possible time frame.

An example of a customer specified new construction is the UHV-Raman-STM System
shown above. The system includes a semi plane parabolic mirror as well as sample
and tip exchange mechanisms (there is a separate page describing it). The parabolic
mirror for focusing is placed on a self developed, UHV compatible, 5 axis manipulator
with sub micron step size. Another example is a high temperature AFM (CAHT-AFM),
which works at temperatures up to 800°C (right side, above).
